I've seen the team of announcers change naturally over time (like back to the Rockford days) due to conflicting schedules, declining health, etc... but they've always I've been the best I've seen anywhere. Gone are the great voices of Nick Resich, Sonney Everet, Jim Hazlet, and don't forget "The Yodler" in the morning.
To demonstrate what it really takes to do a good job with the mike, a week after this years AirVenture, Danny Clishm single handedly announced the "Thunder Over Michigan" show at Willow Run Airport. If it weren't for his knowledge, expertise, and all out people skills, it would have been a very disappointing event. Compared to Oshkosh, it was slooooow moving show but he kept it interesting, people focused, and entertained with his vast experience and talent.
To EAAs credit, they will listen to you with an open mind if you think anything at AirVenture can be improved. Thats how its gotten to be as good as it is.
